#2Not quite--this is more a recreation of the Flash Portal clone. i.e. it's all 2D graphics and 2D physics.
I got my hopes up for a moment, preparing to be awestruck. Since I have a TI-89, that's what I think of when I hear "graphing calculator". My TI-89 can do 3D stuff (for instance this fun maze generator game http://www.ticalc.org/pub/89/asm/games/amaz89.zip), it would blow my mind to have anything close to a Portal 3D engine on it.
It's still awesome but not as mindblowing as the title suggests...

#3This looks more like a standard 2d platformer.

#5The graphics are terrible.

It would not be that hard to write a 3D physics engine for a TI-89 calculator (Assuming you already know how to write a 3D physics engine, which I do). Problem is, it would be useless since it will probably take tens of seconds (if not more) to calculate each frame.

It's a 96x64 B/W screen.

#8Awesome! Too bad I gave my TI84 to some girl, after leaving college :(

I would not be so sure. It really all depends on how much physics you want your "physics engine" to have. Rag-dolls? Not likely. Quake 1? Sure, you could do physics to that extent on an 89. The 89's are more powerful than you may suspect, unlike the 84 (seen in the article), they have Motorola 68k's.
Here is an idea of what you can do with a 84's Zilog z80 (warning: long animated gif): http://benryves.com/images/nostromo/bsp/2010.11.28/Walkthrou...

You can get a lot more out of an M68k. (Actually, to be fair, the M68k calculators' larger screen size works against them, but if you are willing to sacrifice graphics you can easily surpass that demo.)

Not bad but it is not a 3D Physics engine. Just a renderer. Not the same thing. Still pretty impressive.
